I am sure life doesn't fit neatly into 50 minute sessions throughout the day for therapists with 10 minutes between (and never going over or starting early, etc. :-) I would rather a T took/made a call than had it on their mind distracting them? I hope the timing wasn't too bad for you, there was a period when you all weren't talking or had finished/not started a topic instead of being in the middle?
